New RO/DI System - Few Questions?

[westwind77]

I purchased a 75GPD RO/DI 5 Stage *PLUS* System from Bulk Reef and I just wall mounted it in the basement. I followed the set up directions but I was curious:
1) How often does the DI media have to be replaced? (I know not all water is the same and it can vary, but a ballpark figure)
2) It came preinstalled with an IN and OUT TDS meter. The meter is installed right after the RO and after the DI chamber, I take it that this is normal? I was curious what my TDS was going into the system, not just out the RO and out the DI chamber. Do people install a 3rd to know how poor the water is going in?
3) What should my readings be exiting the RO and then again exiting the DI chamber?
4) My water pressure into the system shows 64

based on that I do NOT need an additional pump to raise the pressure,

I might have more but that is it for now, oh, and THANK YOU to this group for helping me make my purchase. I was running an API tap water filter DI chamber before this, but I am sure this will be better!

havent changed mine yet, had it 6 months. You want to change it when your TDS is high
2) It came preinstalled with an IN and OUT TDS meter. The meter is installed right after the RO and after the DI chamber, I take it that this is normal?

I have mine setup the same way. Dont really care what TDS in is, RO out is 1, DI out is 0. If you are curious, just connected the TDS to your water in. Easy to take it off and move it with quick connects.
3) What should my readings be exiting the RO and then again exiting the DI chamber?
Mine are 0 and 1. You may vary but you want as low as possible.
4) My water pressure into the system shows 64

based on that I do NOT need an additional pump to raise the pressure,

about once a year, depending on how much water you are making (size of your tanks)
2) It came preinstalled with an IN and OUT TDS meter. The meter is installed right after the RO and after the DI chamber, I take it that this is normal?

Just remove the RO out TDS line and connect it to the incoming water. Mine was already like this, but it's no big deal to move.
3) What should my readings be exiting the RO and then again exiting the DI chamber?
exiting RO, I have no idea. Exiting the DI, "ZERO" is ideal. When it starts creeping up to 2 or 3, I change the resin.
4) My water pressure into the system shows 64

based on that I do NOT need an additional pump to raise the pressure,

This is excellent. I get 30, at best.

Good luck and hope this helps...

Thanks for the responces! According to the display I have 001 out of the RO and 000 out of the DI.
Before I bought my unit I called my towns water department, they said the average water pressure it usually between 60 - 80, so I was crossing my fingers I was not in some wierd low area.
